Abstract

La présente invention concerne un dispositif mélangeur de fluides qui comprend au moins une unité mélangeuse de fluides; un orifice d'entrée de fluides présent sur ladite unité mélangeuse de fluides, lequel orifice d'entrée de fluides est conçu pour être en contact avec les mélanges de fluides; une unité de décharge de fluides, laquelle unité de décharge de fluides est conçue pour être en contact avec lesdits mélanges de fluides; une paroi inclinée disposée autour de la périphérie dudit orifice d'entrée de fluide; et une unité d'induction, qui induit le fluide, qui s'écoule dans un sens dirigé vers le centre de l'intérieur du dispositif, à former un vortex le long de ladite paroi inclinée. Selon l'invention, on obtient un mélange de fluides naturellement mélangés en n'utilisant la dynamique que d'un seul fluide, ce qui évite d'employer des agitateurs ou des dispositifs d'agitation séparés nécessitant pour fonctionner un apport d'énergie supplémentaire ou séparée.
